    摘要： In a light communication system in which data to be transmitted is converted to an amplitude-modulated light signal which is radiated to a space, and the radiated light signal is received and demodulated to reproduce the original data, the amplitude-modulated light signal is transmitted only for a predetermined period shorter than a unit time of the data to be transmitted.

    摘要： A copying apparatus operable in a two-side copy mode has two exclusive switchback transport paths which are selectively usable for refeeding paper sheets each carrying an image on one side thereof from a refeed tray. One of the switchback transport paths is assigned to paper sheets of size A4 and smaller sizes which are fed sideways, while the other is assigned to paper sheets of sizes greater than A4.

    摘要： A rotating anode X-ray tube is provided which includes an anode disk having a central axis of rotation and a circumferential peripheral edge lying in a plane perpendicular to that axis of rotation. A ring-shaped target is mounted to the disk adjacent the peripheral edge and the disk includes a mechanism formed integrally solid with the disk and remote from the target for mounting the disk to a support shaft of a rotor within a vacuum housing to permit rotation of the disk about the axis of rotation of the disk. The disk is formed integrally solid along the aforementioned plane, including that portion of the disk coincident with the axis of rotation and the disk has a thickness which increases progressively in a radially inward direction from the peripheral edge, including that portion of the disk between the target and the mechanism for coupling, to counteract a radially inward increase in the disk upon high speed rotation of the disk. A cathode is provided for bombarding the target with thermions to generate X-rays which escape the vacuum housing through an appropriately placed X-ray penetrable window.

    摘要： A system and method for determining and controlling the mixture ratio of an air-fuel mixture supplied to an internal combustion engine in which the air-fuel mixture ratio is estimated from a maximum internal pressure of an engine cylinder. The estimated air-fuel mixture ratio is then positively ascertained on the basis of a determination result derived by a weighting processing calculation of input signals indicating various engine and vehicle operating conditions affecting the change in the air-fuel mixture ratio using a weight vector with a reference signal. The air-fuel mixture is controlled on the basis of the ascertained air-fuel mixture ratio. Furthermore, each parameter of the weight vector is learned and corrected in a direction toward which a correct percentage of the determination of the rich-side or lean-side air-fuel mixture ratio by the weight calculation is increased.
